What Are Some Side Effects of Steel Libido?

By Susan Presley

Irwin Naturals produces Steel-Libido, a sexual-enhancement product for both sexes. It purports to increase erectile function and sex drive in men and orgasm intensity and sex drive in women.

Steel-Libido should be taken with medical supervision.


Steel-Libido contains herbs, amino acids and dimethylglycine. The active ingredient is yohimbe, an herb that comes from West Africa.

Common Side Effects

Yohimbe's most common side effects are nausea, vomiting, rapid heart rate (tachycardia), high blood pressure, dizziness, anxiety and insomnia.

Rare Side Effects

Side effects that have been reported less often include seizures and renal failure.


Pre-existing conditions can make yohimbe dangerous for a patient. These include heart, kidney or liver disease. Pregnant and nursing women should also avoid Steel-Libido and other yohimbe-containing drugs. Patients with psychological disorders should consult their physician before ingesting yohimbe.


The effect of certain antidepressants can be increased by yohimbe, which can increase the side effects. Yohimbe-containing products should be taken under doctor supervision.
